Myiasis is the infestation by larvae of flies. Myiasis may involve the skin, eyes, nasal passages, gastrointestinal and enitourinary tracts. Cases of urinary myiasis are very rare mostly occurs in immunocompromised hosts, those with previous urologic instrumentation or those with poor socioeconomic status.

Introduction
Myiasis is defined as invasion of the body by the larvae of flies, characterized as cutaneous
(subdermal tissue), gastrointestinal, nasopharyngeal, ocular, or urinary, depending on the
region invaded [1]. Any infection due to invasion of tissues or cavities of the body by larvae of
dipterous insects [2]. The disease occurs predominantly in rural areas and is associated with
poor hygienic practices. Myiasis producers can be divided into three classes:
A. Obligate parasites requiring living tissue for larval development.
B. Facultative parasites whose larvae usually develop on carrion but may invade
wounds and
C. Accidental myiasis [3]-which commonly is enteric, resulting from swallowing
eggs or larvae with one’s food, i.e. pseudomyiasis can happen when eggs or larvae are
accidentally deposited on oral or genitourinary opening.
Classification
A. The classical description of myiasis is according to the part of the host that is
infected. This is the classification used by ICD-10 [4]. For example:
a. Cutaneous (B87.0)
b. Nasopharyngeal nose, sinuses or pharynx. (B87.3)
c. Ophthalmic or ocular in or about the eye (B87.2)
d. Auricular in or about the ear (B87.4)
e. Gastric, rectal, or intestinal/enteric for the appropriate part of the digestive system
(B87.82)
f. Urogenital (B87.81).
B. Another aspect is the relationship between the host and the parasite and provides
insight into the biology of the fly species causing the myiasis and its likely effect. Therefore,
the myiasis is described as either [4].
a. Obligatory, where the parasite cannot complete its life cycle without its parasitic
phase, which may be specific, semi specific, or opportunistic.
b. Facultative, incidental, or accidental, where it is not essential to the life cycle of the
parasite; perhaps a normally free-living larva accidentally gained entrance to the host [5].

Case Report
Two females aged 34 and married, and a fifteen-year-old
complained about the passage of worms in urine intermittently
during the last t weeks on Spring 2017. They were in good health
and non-diabetic nor having chronic illnesses. In addition, they
reported mild dysuria, no fever and no itching. The urinalysis test
showed 4 to 7 pus cells Per High Power Field (PHF), no significant
Red Blood Cells (RBC). An ultrasonography was done for both
patients with no significant findings. The worms pass mostly at
early morning, i.e. voided urine, so the early morning urine sample
collected is examined, tiny worms could be spotted by a naked eye 3
to 4mm in length, Microscopic examination showed multiple larval
stage of Musca domestica (Housefly)in the sample (Figures 1 & 2).
Figure 1:
Figure 2:
In the detailed patients’ history, it was stated that all of them
used to let their underwear dry in the air. As a result, the Fly lies its
egg on the fabric (underwear), the egg hatches in this kind of humid
worm environment and passes easily into the bladder within few
hours. Patients were asked to avoid drying their underwear outside
or ironing it prior use, in this way the worm disappeared, simple
antibiotics were employed to overcome a secondary bacterial
infection. and adequate control of the fly propagation at home was
attained.
Discussion
Myasis can be caused by many types of fly and might be widely
distributed as cutaneous laryngeal, ocular urinary myiasis is very
rare and can be caused by several agents, such as:
A. Larvae of Fannia scalaris [3] is the most frequent cause of
urinary myiasis [6].
B. Lucilia sericata [7].
C. Eristalis tenax [8,9].
D. Psychoda albipennis [10].
Accidental myiasis mostly happens when eggs contaminate
the underwear or the fly deposits its eggs on the genital organ, the
humidity and warmth let the eggs hatch and forming larva that can
pass directly into the bladder, and void urine next morning. Urine
myiasis is recorded mostly in women [11], since their short urethra
mayfacilitatethepassageoflarvatothebladder.Urogenitalmyositis
with different fly species has been reported in developing countries,
especially in tropical/subtropical regions such as Malaysia, Algeria,
Spain, Brazil and Iran [12], Saudi Arabia [13], India [14,15], Egypt
[16] and Romania [17-20].
Psychoda
Clogmia(Telmatoscopus)albipunctataisaprimitiveNematocera
of the family Psychodidae, subfamily Psychodinae which are non-
biting moth flies known as drain, and bathroom or filter flies [13].
Clogmia albipunctata is cosmopolitan in distribution; the adult flies
are often seen in moist places, especially bathrooms and toilets
[14-16]. However, it is rarely encountered in humans with cases of
urogenital myositis originating from P.
Albipennis
P.albipennis ‘s body, not exceeding 12mm in size, is covered with
gray brown dense hairs. Adult flies, especially in humid toilets and
bathrooms, leave their eggs on stones and other solid objects in
moist and dim areas. The larvae are found especially in damp and
dirty areas, deteriorating vegetables and fruits, garbage piles and
sewage plants. There are four developmental stages of larvae of P.
albipennis that emerged from the laying under suitable conditions.
The larvae change their shirts three times to the pupa stage. In the
urine of infested people, fourth period larvae of 4-8mm in size,
which are scattered locally, can be seen [12]. To our knowledge
this the first report of human urinary myiasis caused by Clogmia
albipunctata in Egypt and the second case worldwide. This case
draws the attention of urologists and laboratorians of the possibility
of detecting dipteran flies’ larvae in urine and urinary myiasis as an
unusual cause of urinary tract infection.
